A series of DATB (diaximotrinitrobenzine) pressings were made in an effort to find the most suitable binder. The requirements for this binder were as follows: Thermal stability (Must be as stable as DATB or not show any reaction with DATB at 200 degrees C); Density (Must press to 95% theoretical or higher); Compressive Strength (Must be strong enough to machine, and stronger if possible); Moldability (Must be adaptable to isostatic pressing conditions). After investigating various materials such as epoxies, a high temperature silicon phenolic and Exon, it was found that, DATB could not be pressed at 110 degrees C and 20,000 psi to an acceptable density and strength. While a plastic binder is not needed for reasons of strength or desensitization, it may however be needed as a plasticizer to resist thermal shock. This can only be determined by the production of larger specimens at Site 300. Summarized data is presented
